LANSING - A Lansing man who was ejected from his vehicle during a rollover crash early Monday morning and subsequently struck by another vehicle is in critical condition.

The crash took place around 12:50 a.m. Monday on Interstate 496 near Capitol Avenue, according to Lansing Police Public Information Director Robert Merritt.

A 27-year-old Lansing man lost control of his vehicle while driving eastbound on I-496, striking a guardrail before rolling over into westbound lanes. The man was ejected from the vehicle.

A 21-year-old man headed westbound stopped to help the injured motorist. His vehicle was then rear-ended by a third vehicle which then struck the injured motorist, according to Merritt.

The driver involved in the initial crash was taken to a local hospital and is listed in critical condition. Both the driver of the vehicle that stopped to help the ejected motorist and a 19-year-old female passenger sustained minor injuries. The driver of the third car did not require medical attention. None of their identities have been released by police.

Lansing's Accident Investigation Team was called in following the crash, which closed I-496 for approximately five hours. Both East Lansing and Lansing Community College's police departments assisted Lansing police at the scene.

The crash remains under investigation.
